 ## parallelism
 
 `number = 100`
 
 Limit the number of parallel processed modules. Can be used to fine tune performance or to get more reliable profiling results.
 
+Lower values reduce concurrent work and memory pressure, but may increase total build time. Higher values can improve throughput on powerful machines.
+
+**webpack.config.js**
+
+```javascript
+export default {
+  // ...
+  parallelism: 50,
+};
+```
+
+Use cases:
+
+- Reduce `parallelism` when builds hit memory limits (for example in constrained CI runners).
+- Increase it when you have enough CPU and memory and want to maximize build throughput.

 ## profile
 
 `boolean`
 
 Capture a "profile" of the application, including statistics and hints, which can then be dissected using the [Analyze](https://webpack.github.io/analyse/) tool. It will also log out a summary of module timings.

+```javascript
